PATE IO HCE i 8 WILLIAM L. HAMILTON, or BA GOR, MICHIGAN SPRAYEQR Application filed April 18, 1927, Serial No. 183,360...Renewed January 5, 19 31. A

The main obj ectsof this invention are:

First, to provide a sprayer for the spraying of fruit trees and the like in which the character of the spray may be very greatly c varied. v

Second, to provide a sprayer having these advantages which is adapted to handle a large volume of liquid, is not likelyto become clogged and is easily operated to vary the-character of the spray. j I

Objects pertaining to details and economies of my invention will definitely appear from the detailed description to follow. The invention is defined in the claims.

15} A structure embodying the features of my invention is clearly illustrated in the accom- I panying drawingsforming a part of this application, in which: p

Fig. 1 is a fragmentary view of my .1II1- proved sprayer partially in longitudinal section on a line corresponding to line 1-1 of Figs. 2, 3 and 5.

Fig. 2 is a plan view of a sprayer head em- 2; bodying myinvention, the nozzle or head tip being removed.

Fig. 3 is a a line corresponding to broken line 3-3 of Fig. 2.

Fig. 5 is a sectionon line 55 of Fig. 1 showing details of the valve operating means.

horizontal section on line of Fig. 6 is a detail view mainly in longitudis nal section of a modified form or embodiment of my invention;

Fig. 7 is a transverse section on line 77 of Fig.6.

In the embodiment illustrated in Fig. 1 I show my improvements as I have embodied the same in a multiple head-sprayer. The I structure comprises a U-shaped body member 1 having a chamber 2 therein, each arm terminating in a head 3 upon which the nozzle tip 4 is threaded. This nozzle tip has a central dischargeopening 5 therein.

- 8 The head 3 is provided with a central cylin-c drical bore 6 with longitudinal channels opening thereto. This bore 6 is, in effect, a central delivery port for the head. The

channels 7 are provided with-oppositely disfragmentary viewin section on posed inclined slot-likedelivery ports 8 openingv to the bore 6 at their inner ends The ports 8 are'formed in a transverse wall 9 in the head, the wall constituting the end walls for the channels or passages7.

The port 6 is controlled bythe plunger 10 which reciprocates therein and may be retracted to allow the fluid to flow through the port 6 as well as through the ports 8, the ports 8 always being open, the plunger however closing the inner ends of the ports when the plunger is in the position shown ingthe drawlng in which'position the valve is closed during. asubstantial opening movement of the valve. By this arrangement I provide a sprayer having Verywide variation in the character of the spray, this'being controlled by the adjustment of the plunger. "'i-When the plunger is fully retracted a long narrow spray V results. As it is moved to entirely close the port 6 a wide fine spray results. Adjustment between these extremes results in varying the character of the sprayi Also, of course the force under whichthe fluid is delivered affects the character of the s ray. Should the ports 8 become clogged tliey may be very effectively freed by fully withdrawing the plunger as this not only allows a full stream ofwater to flow but opens the inner ends of these ports so that the wedging action of the clogging material is relieved.

As the heads are duplicates adescription of one will suflice. i y

The body member 1 is provided with an inlet port 11 which is controlled by the valve 12, this valve being connected to the yoke 13 disposed in the chamber 2 so that the lunger and valve are simultaneously operate The supply pipe 14 is connectedto the collar 15 surrounding the port 11. The stem. 16 is connected to the handpiece 17 which is threaded for adjustment by means of a swivel consisting ofthe guide member 18 reciprocating in the conduit 14 and having a recess 19 therein engaged by the'head 20 on the shank 21 of the handpiece 17. I This swivelconnection is a matter of convenience asitcpermits the firmgrasping of the handpiece 17 and manipulation of the sprayer without aflecting the valve, the valvebeing operated by a 7 Patent 1s longitudinal movement only. If the handle were non-rotatable, more or less strain would be placed on the operators wrist in swinging the sprayer about or it would be necessary for the operator to allow the grip to turn in his hands.

I11 the modification shown in Figs. 6 and 7 the head 22 is provided with a collar 23 to receive the conduit 24, the head having a wall 25 with a port 26 therein opening to the bore' ments of my invention which I consider very practical. I have not attempted to illustrate or describe other embodiments or adaptations which I contemplate as I believe the disclosure made will enable those skilled in the art towhioh my invention relates to embody or adaptthe same as may be desired.
